2. Product Overview
JW-RD-600(HJ03) Radar Flow Meter is designed for continuous non-contact monitoring of open-channel flow. It integrates radar surface velocity measurement and radar water level measurement into one compact device. By combining velocity data, water level data, and channel cross-section parameters, it can calculate real-time flow rate for hydrology, flood control, drainage, irrigation, and water conservancy applications.
Compared with contact-type flow meters, this radar flow meter does not require installation in water, which reduces maintenance risks and improves long-term reliability in complex field environments. It is especially suitable for sites with high flow velocity, muddy water, floating objects, sediment, or difficult maintenance conditions.
For remote monitoring projects, the integrated RTU version can transmit data directly to cloud platforms or monitoring centers through 4G, NB-IoT, or LoRa. It also supports multiple industry protocols, making it suitable for integration with government hydrology systems, smart water platforms, and IoT monitoring networks.
The radar flow meter supports multiple output and communication options for different project requirements. Standard RS485 with Modbus protocol enables easy integration with RTUs, data loggers, PLCs, and IoT gateways. Optional RS232 and SDI-12 interfaces are available for hydrological and environmental monitoring applications.
For remote monitoring stations, the integrated RTU model supports 4G, NB-IoT, and LoRa wireless communication. The device can transmit flow velocity, water level, and calculated flow data to cloud platforms or government water monitoring systems through SL651, SZY206, MQTT, HJ212, HTTP, or customized protocols.
4. Application Scenarios
River and Lake Hydrological Monitoring: Used for real-time flow monitoring in rivers, lakes, reservoirs, natural water bodies, and water resource management stations. It supports long-term hydrological data collection for flood forecasting and water allocation.
Flood Warning and Disaster Prevention: By measuring water level, surface velocity, and calculated flow at the same monitoring point, the radar sensor helps operators identify abnormal changes in river and drainage conditions. It can be combined with rainfall monitoring and automated alarms in a river flood monitoring system.
Irrigation Canal and Drainage Monitoring: Applicable to irrigation canals, drainage channels, sluices, culverts, and water conservancy projects where stable non-contact flow measurement is needed.
Ecological Flow Monitoring: Used for ecological discharge monitoring in rivers, reservoirs, and hydropower-related projects to support water resource regulation and environmental compliance.
Urban Waterlogging and Sewer Outlet Monitoring: Can be installed in urban drainage channels, underpasses, sewage outlets, culverts, and low-lying roads to support waterlogging early warning and emergency response.
